Only three that i'm aware of, mine.. the SMC, and the Snow piece. The SMC and the Snow units are 99.00 and limited to 20 PSI for range. So it wont add anymore alky after 20 PSI. Also the ramp is not adjustable. They do have variable turnon points..off course. I also can guess based on price they both are the same unit.. but cannot confirm since clear pictures are not available. And or confirmation from Steve or Snow.
Lastly no brake input for launch assist.
I have never seen any status report/findings/data on the SMC one. No information .. cept it ramps the pressure.
It takes me on average 5 hours to build one of mine.. cant comment on the others. Guys buying mine rely on it to keep theyre $10,000+ motors together. Soon price will go up. Just an FYI.
